mp3 was 15/0 over 40 hands and BB was 27/13.

I'm finding a lot lately that I am playing hands like this pretty damn passively, and don't even notice until I re-read the HH. I guess I was fearful of KQ? Maybe even AK (even though I do outdraw that on the turn) since mp3 was soooo passive and never raised pf. I gave KT or a hand like that a good chance to catch up. Would anyone else check the turn/river here? With stats on mp3 is check/calling here a decent line? Value bet river?
